Big Numbers

this is what I’m reading through right now: “A variant on the compressed sensing of Emmanuel Candes,” by Yves Meyer and Matei Basarab. I’m not done with it, but it involves reconstructing a function by sub-Nyquist sampling of its Fourier coefficients, using an -minimization technique. It’s a generalization of a theorem by Terence Tao about functions on finite fields. Looks to be interesting.
